To (MZ A117mm it may concern:

Be it known that I, ALBERT PETEREIT, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Swings forElectricLight or Telephone Brackets and Similar Devices, of which thefollowing is so full, clear, and exact a description as will enableothers skilled in the art to which my invention appertains to make anduse the same, reference being had to the accompanying drawings, inwhich- Figure l is a side elevation, with parts broken away, showingconstruction in section. Fig. 2 1s a side elevation of the male nipple.Fig.

is a side elevation of the female split nipple. Fig, 4 is an end view ofthe same. Fig. 5 is a sectional view of the lock-nut. Fig. 6 is a top orplain view of the telephone-transmitter bracket.

The object oi' my invention is to furnish. a swing which maybe adj ustedto revolve easily, with increased resistance, or one which may be set orlocked in any positive predetermined position and the lever or handleremoved to prevent a novice or one not familiar with the device fromtampering with it and getting.

it out of order. W hen swinging brackets of ordinary construction areplaced on partitions, desks, or other places which are not ri gid andsusceptible to vibration,the bracket is liable to be moved accidentally,and some means must be provided for quickly locking and unlocking it,and such means is provided by this invention, which makes the bracketmovable or stationary, as may be required or desired, at will.

In the accompanying drawings, A is a back plate into which thesocket-support B is secured.

C designates a Vhollow externally double compressible screw-threadednipple which secures a quick adjustment. The nipple is slotted,as shownin Figs. 3 and et, at a, and has a clear smooth beveled edge Z) at thetop. This nipple is secured to the support B and is encircled by alock-nut or compressor G,thread ed internally part of the way up tocorrespond with the double screw-threads on the nipple upon which itscrews. It may be provided with one or more handles C2. This lock-nuthas a smooth beveled portion near its upper edge on the inside tocorrespond with and inversely to the bevel on the top of the nipple, asshown at c.

E designates a male nipple forming the b'alance of the swing, slightlytapering,its largest diameter being at the bottom. This tapered end fitsinto the upper end of the nipple C and has a shoulder which rests on theupper end of the nipple C. A tube F is fitted into the side or top ofthe male nipple E, and when the end nozzle or other finishing-piece issecured to the free end of the tube the bracket is completed. 1When thelock-nut is quite loose,the joint will revolve freely,but cannot beaccidentally displaced. Then it is desired to have it remain in anyposition in which it is left, the lock should be slightly tightened,which is done by screwing the lock-nut C' down slightlyon the threadednipple C. The upper end of the nipple C will be closed by reason ofits'beingpeveled at the top and coming' into contact` with acorresponding bevel on the top at the inside of the lock-nut, and theslots will enable the parts to be brought together-,Creatin g frictionon the tapered sides of the section E, which cannot then be lifted outor removed, and when the lock-nut is tightenedstill more the friction isso great that the joint ceasesr to rotate and will stay in any positionin which it may be left. YVhen it is desired to leave the bracket .in aiiXed position permanently and the proper friction to make the jointswing nicely has been obtained by the adjustment of the lock-nut, thehandle or handles may be unscrewed and removed, as the screw-threadswhich are shown at G will permit, and then the lock-nut cannot be movedexcept by tools or by replacing the handles.

It will be readily understood that this invention is adaptedto be usedwith vrequal facility in transmitter-brackets for telephones. The swingand locking device operate equally as well in either a vertical orhorizontal position.

It may be readily and easily wired by taking out the tube and swingingthe part E and drawing the wire through, leaving sufficient wire free topass down into and through the IOO back plate. 'Vlhe section 'E is thenput vin place and the leek-nut tighte1'1ed and the braeket adjusted. asdesired.

IIaving described the objects, uses, and advantages otf my invention,what I believe to be new, and desire toseeure by Letters latent otl theUnited States, and what l therefore claim, is-

l. As animprovement in swings li'oreleetrie lights and telephones, ajoint, consisting ort.' a slotted hollow main seotion or soeket; Vinoombination with a renmvable section adapted to be supported in thetirst section7 one ot' said seetions provided with a shoulder forming abearing-surfaee,tor supporting the second seetion vertically, and aCompressor t'or eompressing the slotted. nipple around and upon theseetion which is secured Vwithin the lower seetion, substantially asdeseribed.

A main support provided with athreaded slotted nipple tapered at oneend, in eombination with a lock-nut eorresijiondingly and inverselytapered on the inside and adapted to compress the slotted nipple to lockthe tixture in place with a straight-sided, non-serewthreaded removableseetion or iixture provided with a shoulder abutting against the outerend ot:- the slotted nipple and. being depressed at a point below theshoulder and within the plane ot' a line drawn from the outer peripheryoli' the shoulder to the outer periphery oli' the movable seetion belowthe said depression, and adapted to iit revolubly within the slottedsupport, and adapted to be revolved an unlimited number oi times in onedirection and in the same `horizontal plane, said removable seetionfitting snugly against the inner wall of the slotted section below andsmaller than the inner diameter of the slotted section at and near thetop oi' the split section., substantially as described.

I3. As an improvement in swings :l'or eleetrie lights and telephones, amain supiriort; in i eo111bination with a slotted nipple, tapereill atits upper end and a lockamt eorrespondingly ltapered on the inside andencircling the slet ted nipple and a supplemental plug, having ashoulder whieh :rests on the top ot' the slotted nipple, thesupplemental plug extending into the slotted nipple7 substant'iallyr asand for the purposes speeilied.

-;I-. As an improvement in swings t'oreleetrie lights and telephones, amain support provided `with a coinl'iressible nipple having a break inits outer end and screw-threaded exteriorly; `in Combination with alock-nut adapted to embrace said nipple and to eompress it at its outerend by being turned upon it and a tapered supplemental nipple, having ashoulder which rests on the eompressible nipple, adapted to support thetrans111itter or light arm, substantially as described.

Asanimlrnovement inswingingsupports lor eleet ric lights and telephones,a main support, externally threaded and provided with a split ni pple,the upper outerportion oi which is smooth and inwardly tapered and ani11- teriorly-tl1readed lock-nut having a smooth tapered surface,adapted to engage and cont press thel s111ooth tapered sections oi thesplit nipple7 for lessening thediameter ot" the nipple to look the armolf the swinging supportV at any desired point and against aeeidentaldisplaeement at all times; .in combination with a second section whoseouter eireinni'erenee at the top is less than the inner normaleireumt'erence of the split section, leaving a space between them, saidsecond section adapted to [it snugly within the split nipple, below thetop, substantially as described.

In testimony whereof I at'tix my signature in the presence of twowitnesses.
